Yeti Krab

Yeti Krab is a character who appears in the season 9 episode "Yeti Krabs." The Yeti Krab greatly resembles Mr. Krabs but with a different nose and grey hair around his neck.
In the episode, he was first just told as a fictional character in a story by Mr. Krabs to get Squidward to work harder, but SpongeBob believed it was true so he started working in overdrive, but it ends up that the Yeti Krab is actually real. The Yeti Krab is based off a real animal, called the yeti crab, which was discovered in 2005.
